What are the advantages and disadvantages of duck down?
Advantages of duck down:
1, high bulkiness: duck down is very bulky, and a lot of air is stored in the middle to avoid heat loss caused by air flow.
2. Thermal conductivity: In addition, the thermal conductivity of duck down itself is very poor, which prevents the heat loss caused by heat conduction. Therefore, the warm-keeping performance of duck down is particularly good.
3, low density: because ducks have two kinds of hair, the outer layer is outer hair, and the surface layer has a layer of oil to prevent the inner feathers of ducks from being easily wet by water when they enter the water! It also has a maintenance function! It's called duck down, which mainly plays the role of heat preservation. They are thin, dense and light.
3, good air permeability: but only duck down can keep warm, because the relative density of duck down is small, so it has less air permeability and better warmth retention.
4. Good warm-keeping effect: The warm-keeping effect of the white duck down coat is particularly good. The most effective component of white duck down jacket is down jacket fiber-natural protein fiber from waterfowl.
5. Stable structure: The reason why down fiber has good warm-keeping performance comes from its unique bifurcated shape and structure, which leads to its high bulkiness, and then has strong ability to contain electrostatic gas.
